Save you do huge hours per season I doubt a 4 stroke would "use" less
oil than one of the new epa compliant 2 strokes but you might also consider;

I will create some charts and post ... Besides the ETEC they all use
lots of oil . My optimax runs at 50:1 - 60:1


(i) The 4 stroke doesn't put oil out into the air or the water, it gets
"changed". Hopefully the used oil gets disposed of correctly, here
that's mostly take it to a garage for their recycle tanks.

Yes true ... this time however cost is the only objective

I am unsure which is worse: 2 stroke oil burnt or 4 stroke oil in the
landfills in form of oily rags and filters which most people dont
dispose properly (assuming they recycle the actual oil)


(ii) You should at least once a season clean out the oil reservoir on
the 2 strokes (new or old type), the oil in a vented tank absorbs
moisture which creates a sludge in the bottom of the tank.

Yikes! I didnt know that ... how is that done? flush it with oil?


(iii) The "new" 2 strokes use or at least recommend special dealer only
oils; can be expensive.

They ARE very expensive. Although you can run an optimax on the
(relatively) cheap oil it is STRONGLY not recommended ....

Thanks for your good input!
